@schnurlos:
dil101-177.fi.nor.wanidarum.com and svaio-12.dyn.pool1.garodo.net I have seen in μTorrent and I myself have searched for a long time to determine them ... I found at least some information on https://www.abuseipdb.com/whois/213.136.79.7 and https://www.abuseipdb.com/whois/213.136.79.238
And the domain name of both contabo.de... But it's up to you, of course.
